Subject: fix 64-bit syscall argument passing on or1k
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=de2b9c21d94e0b76b629fec0060d043f535eef01;p=musl

fix 64-bit syscall argument passing on or1k

the kernel syscall interface for or1k does not expect 64-bit arguments
to be aligned to "even" register boundaries. this incorrect alignment
broke truncate/ftruncate and as well as a few less-common syscalls.
